hazardFun: Hazard functions for gamlss.family distributions

Description

The function hazardFun() takes as an argument a gamlss.family object and creates the hazard function for it. The function gen.hazard() generates a hazard function called hNAME where NAME is a gamlss.family i.e. hGA().

Usage

hazardFun(family = "NO", ...)
gen.hazard(family = "NO", ...)

Arguments

family

a gamlss.family object

…

for passing extra arguments

Value

A hazard function.
